Cicadella viridis, sometimes called the "green leafhopper" (but not to be confused with Nephotettix a genus that includes rice pests), is a species of European leafhoppers belonging to the subfamily Cicadellinae. This species is present in most of Europe, in eastern Palearctic realm, in the Near East, in the Nearctic realm, and in the Indomalayan realm.
These leafhoppers inhabit rough grassy areas, peat bogs and mires, wet meadows, near marshes or in swampy habitats, but sometimes live also in drier areas. The adult males of Cicadella viridis can reach a length of 5.7–7 millimetres (0.22–0.28 in), but the females are quite larger than the males, reaching 7.5–9 millimetres (0.30–0.35 in).
Their pronotum and scutellum are green and yellow. The front head is pale yellow, with two black spots near the compound eyes. The forewings are turquoise green in the females, blue or dark bluish in males (sexual dimorphism). The abdomen is bluish-black.
The larvae are yellowish and have two brownish stripes running from head to the end of the abdomen. Adult leafhoppers can mostly be encountered from July through October. These leafhoppers... Wikipedia →

Rare
Under 5% of wildlife watchers report a Green Leafhopper sighting in Seoul on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 353rd most-seen of the 525 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
May and July
In those months about 10% of wildlife watchers report a Green Leafhopper in Seoul on a given day, against under 5% in June and August–April, the lowest months. Those are among Seoul's wettest months, with about 220 mm of rain a month against 20 mm in January.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Green Leafhopper sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
18th of 25
Of the 25 cities where we can rate Green Leafhopper sightings, Seoul ranks 18th at under 5%. The best odds are in Manchester (United Kingdom, about 10%), Porto (Portugal, about 10%) and Turin (Italy, about 10%).
GBIF citizen-science records
It is estimated from how often the Green Leafhopper is recorded against all the insects logged in Seoul (8 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
